JOINT FOR KnocKnowN era-corneas.

Application filed April '24, 1926; Serial No. 104,259.

This invention relates to a joint for knockdown; structures and more concealed joints therefor.

It contemplates more especially the provision of a novel means for effecting. with ease-a rigid concealed joinder of two or more adjacent members so as to render a pleasing and harmonious in I detween cooperating elements, and to effecti'vely conceal them from view in devices wherein apleasing and aesthetic appearance is essential or at least highly desirable.

Further, the joints of known construction have not proved entirely satisfactory for structures of the knock-down type, for these must necessarily be assembled and dismantled with ease and without entailing much labor and time.

One object of the present invention is to simplify and improve the construction of devices of the character mentioned.

Another object is to provide improved concealed connecting means for members constituting a rigid structure;

A further object is to provide an improved constructionof devices of the character mentioned whereby the parts thereof may be easily assembled and dismantled.

A still further object is to provide a joint which is simple, inexpensive, durable, and of pleasing appearance.

In the drawings: 1

Figure 1 is a perspective view of a knockdown structure wherein concealed connecting means for the constituent elements, are

' highly desirable.

Figure 2 is a perspective view of a joint embodying features of the present invention.

Figure 4 is a view in elevation taken substantially from line IVIV of Figure 3,

particularly to ards- 10 in the customary manner.

the usual corner standards 10, to which are secured in a manner to be hereafter de scribed, spaced horizontal members 11 posig tioned near,v the top and bottom of the stand- The radiator cover in this instance, has a top 12 which rests upon the standards 10 in an obvious manner so as to cover a radiator 13 or the like for the from view.

Sheeting 14 of any pleasing or desirable design is,'in this instance, secured to the members 10 and 11in any appropriate man-;

ner so asto occupy the'space intermediate purpose bof shielding it the frame defined by the members 10and 11. As shown, the standards 10 are-angular in cross 'sectionso. as to present right angularly related faces to which are secured on the inner sides thereof securing means-to make possible a simple concealed connection between the members '10 and 11 constituting the frame of the structure above described. V

The securing means, in this instance, com prises a member or bracket 15 which is bent along a median line thereof to'present a corner edge 15 which constitutes the inter,- section of the angularly related 'faces 16 and/17 thereof. One of the sides,'in this instance 17, is provided with a mortise'havinginclined sides 18 and 19- which communicate with a slot 20 formed in the edge 15 so as to receive therethrough'the member 11 which is provided with a correspondingly shaped projecting tenon 21 which is adapted 'to project through the slot 20 to interengage the mortise defined by the inclined sides 18 and 19, when positioned therein. As shown the face 17 is anchored to a face of the standard 10 in any appropriate manner as by the threaded studs 22. It is to be noted that the bracket 15 maybe weld-ed or otherwise secured to the standard 10.

A plate 23 which approximates in size the face 16 of the bracket, is adapted to be detachably secured thereto in any suitable manner so as to maintain the tenon 21 in the mortise thereby rendering the members rigid. The plate 23 is in this instance secured to the face 16 of the bracket by means of the screws 24 which are adapted to extend through the spaced apertures 25 provided in the face'16 for that purpose.

. A stud '26 may be provided in theii'ace of the standard to engage an aperture 2? inthe member 11 atapoint removed from the bracket to further reinforce the struc- Obviously, the studs 22 and .26 may ture. be welded or otherwise secured to the interior of the standard lOor they may roject therethrough and be provided wit a medallion to obscure the studs from vision.

With the arrangement of parts above described, it will be apparent that a simple and effective concealed joint has been provided which is capable of being assembled and dismantled with ease by merely seand positioned in the mortise.

' I claim:

1-. In a device of'the character described,

a pair of members, means on one of said members to slidably receive the other or said members, and cooperating means associated with said means and slidable mernher to effect engagement therebetween in a predetermined position.

- 2. The combination with a pair of members, of a bracket anchored on one of said members, said'braeket' having a slot to slldably rece ve the other of sald members, and

interfitting means associated with said slidable member and said bracket to effect engagement therebetween subsequent to the" reception of said member. by said bracket.

3; The combination with a pair of members, of a bracket anchored on one of said members, said bracket having a slot to slidably receive the other of said members, 1n-

"terfitting means associated with said slidable member and said bracket to effecterr gagement therebetween subsequent toi the reception of said member by said bracket,

and means secured to said bracket to maintain said slidable member and b-racket in interfitting rigid relation.

.4. The combinat on wltha pair .otmembers, of a bracket associated with one of said members, theother of said members projecting into said bracket, a mortise formed in said bracket, and a tenon corresponding to said mortise on the projected portion of said member to engage. said mor communicating with said slot, and a correspending tenon on the pro ected portion of said member to engage said mortise.

6. The combination with a pair of members, of an angular member constituting a bracket associated with one of said members, said bracket having a slot formed in the bent edge thereof, the other of said said bracket,a mortise having inclined sides communicating with said slot, a corresponding tenon on the projected portion of said member to engage said mortise, and a member secured adjacent one face of said bracket to retain said mortise and tenon in engage ment.
